Calcifying odontogenic cyst was first reported by Gorlin et al. in 1962. It had been classified as a neoplasm related to the odontogenic apparatus because of its histological complexity and morphologic diversity until it was renamed calcifying cystic odontogenic tumor by the WHO in 2005.<BR>We report a case of calcifying cystic odontogenic tumor associated with odontoma that arose in the maxillary sinus of a 26-year-old man. He had no symptoms and was accidentally found to have a well-defined radiopaque mass in the left maxillary sinus on pantomography. Computed tomographic examination showed that the entire lesion occupied about two thirds of the sinus. An odontoma-like mass was present at the base of the maxillary sinus, bordered by a cystic lesion. The vast majority of these clusters were wrapped in bud-shaped hard tissue. When the lesion was excised, the hard structures were split, and the cystic lesion was removed en bloc. The specimen measured 40 by 35 by 30mm. Histopathological examination revealed compound odontoma and a cystic tumor including ghost cells and cartified tissue. The exterior hard tissue was woven bone.
